Crankshaft horizontal output general gasoline engine

Abstract

The invention discloses a crankshaft horizontal output general gasoline engine comprising an engine body. A panel and a silencer outer cover are arranged on one side of the engine body. An oil tank body is arranged on the other side of the engine body. The oil tank body is sleeved with an oil tank outer cover. The panel is arranged on the front end face of one side of the engine body. The silencerouter cover is located on the panel, and the front end of the silencer outer cover is buckled on the upper end face of the panel. The left side of the oil tank outer cover and the right side of the silencer outer cover as well as the right side of the panel are buckled. The crankshaft horizontal output general gasoline engine has the advantages of being ingenious in design, simple in structure and low in cost. The crankshaft horizontal output general gasoline engine is adopted, thus assembly is convenient, and assembly efficiency is improved. In addition, immersion of rain and snow is prevented effectively, meanwhile, immersion of the rain and the snow is blocked, so that corrosion and freezing of inner parts due to the rain and the snow are prevented effectively, and operation stabilityof the general engine is improved. In addition, through plastic injection molding, weight is reduced, and manufacturing difficulty is lowered.

Description

technical field [0001] The invention relates to a general machine, in particular to a general gasoline engine with crankshaft horizontal output. Background technique [0002] At present, the existing general-purpose gasoline engine includes an engine body, a panel and a muffler cover are arranged on one side of the engine body, a fuel tank is arranged on the other side of the engine body, and a fuel tank cover is arranged on the outer cover of the fuel tank; the muffler The connection position between the cover and the panel is basically set on the top of the muffler cover; among them, the components such as the panel, the muffler cover, the fuel tank and the fuel tank cover are respectively connected and fixed to the engine body by fasteners such as bolts, which not only makes the structure complicated, but also Moreover, the assembly process is relatively complicated, the assembly time is increased, the assembly efficiency is reduced, and the manufacturing cost is correspo...

AI Technical Summary

Problems solved by technology

The fuel tank with this structure has the disadvantages of complex structure, difficult assembly, and high cost; at the same time, because the bottom of the fuel tank is in direct contact with the tank body, the temperature of the fuel in the fuel tank will also rise accordingly when the body temperature rises during operation. Accelerated the evaporation rate of fuel in the fuel tank, wasting fuel

[0004] And, on the existing general-purpose gasoline engine, the connection between the panel and the muffler cover, the connection between the panel and the fuel tank cover, the connection between the muffler cover and the fuel tank cover, due to structural limitations, the connection between them has a connection gap; In rainy and snowy weather, snow and rain can slowly soak in from this gap, corrode and freeze the internal parts of the general machine, causing damage to the parts
